Natural Factors Ultra Strength RxOmega-3 Review: Potent, Clean, and Surprisingly Easy to Take

Meta: Tried Natural Factors Ultra Strength RxOmega-3 Fish Oil for my joints and heart health — here’s a hands-on review of its real-world benefits and ease of use.

Why I Tried This

I’ve been on the hunt for a trustworthy Omega-3 supplement for a while. Something potent, free of fishy aftertaste, and safe for long-term use. After skimming through forums and buyer’s guides, Natural Factors Ultra Strength RxOmega-3 Fish Oil kept coming up. With 2,150 mg of Omega-3s per serving and a solid EPA/DHA/DPA ratio, it sounded like exactly what I was looking for—especially since it’s made from sustainably sourced wild fish.

First Impressions

Right off the bat, the softgels looked more polished than most fish oils I’ve seen. No weird smell when opening the bottle, and they were easy to swallow. I appreciated that I only needed one or two a day instead of popping multiple pills across the day. Bonus: they didn’t leave me with that dreaded fishy burp, which honestly made me skeptical at first — but I was wrong.

What Stood Out

Three things convinced me this was a keeper: first, no aftertaste. I’ve tried other “high potency” fish oils that left me tasting the ocean hours later. Not this one. Second, my joint stiffness noticeably improved after a couple of weeks. I didn’t expect relief so soon, but getting out of bed in the morning hurt less. And third, it’s ultra-purified and pharmaceutical grade — basically peace of mind in a capsule. I also liked that it's free of gluten, soy, dairy, and artificial ingredients, which checks a lot of boxes for clean eating.

Where It Fell Short

If I had to nitpick, the softgels are on the larger side. They go down fine with water, but if you struggle with capsules, just be aware. Also, it’s not the cheapest option out there. That said, I’d argue it delivers enough value to justify the price, especially considering the high concentration per pill.

Why It Matters

Heart health runs in my family, so Omega-3s are non-negotiable for me. Plus, with a desk job and increasing joint discomfort, I needed something that could support inflammation, brain clarity, and mobility. Natural Factors Ultra Strength RxOmega-3 delivered noticeably on all fronts—it’s not hype. It’s solid, science-backed nutrition that fits into a real-world routine.
